INTRODUCTION
The enclosed resolution is in reference to the public hearing on the 2011 Sewer Cured -in-
Place Pipe (CIPP) Lining Project.
BACKGROUND
DISCUSSION
With age, sanitary sewers deteriorate. Cracks and bad joints form, compromising the integrity
of the sewer. In addition, stormwater and groundwater can infiltrate into the sanitary sewer.
Both conditions can cause the overloading of the City's sanitary sewer system.
The high costs and inconvenience to the public associated with the excavation and restoration
of pavement for sanitary sewer rehabilitation projects has led to the development of
"trenchless" technologies. Cured -in -Place Pipe (CIPP) is a versatile trenchless method for
restoring structural integrity to sewer mains.
CIPP is a resin - impregnated tube that is installed in an existing damaged or leaking sewer.
Once inserted into the pipe, it is expanded and cured by applying heat. The liner is a
seamless, joint -less pipe with a smooth inner surface that increases the flow capacity of the
pipe. The seamless pipe also prevents infiltration. Robotic cutters are then used to restore
private sewer service connections.
The sewers identified for lining as part of the 2011 Sewer Cured -in -Place Pipe (CIPP) Lining
Project are as follows:
Kaufmann Avenue (at Martin)
